The device'for cutting'the nail-bar into proper lengths will be dulyexplained.

isisimilar in its general form to the well-known Singersewiiig-ninohine, although of much greater proportions; that is to say,it is composed of a. base or bed-plate, B,

The necessary reciprocnting rectilinear" movements of the tappctf'zoward and away from the mouldblock are effected as follows:

A horizontal furcated 'tripping-lever orpsllct, y,

- The .ahov'e description embraces the construction and-organization ofmyimproved machine, and will enable skilled or intelligent mechanics, towhom this specification is'chieiiy addressed, to build'it. The operationof the above-described mschine is as follows, inbeing premised with theremark that the iron strip, of which the shoes are formed, is to besuit-ably f'easedfor forming the groove about the nail-holes; andmaintained. at a red heat'while it is fed to the machine, the positionof the difi'erentparts of the'mzn saline being as shown in Figure-liefthe accompanying V driiwiusgs, that is, with the feeding-carriageretracted to its l rthcst cxtcnt, the formers or wings H H wide open,the perch-carrier elevated, and the mould-block and cnlking-bzualsoelevated {it being-remarked that the null-piste has been insert-ed inplace between theclump-bar ji, and the ieeding-cnrringe g and pushedinward until it strikes against the stop or gauge 12:, before mentioned,and that the punch-carrier has first made one descent; and cut apieceffrom ofisuch strip, length sutiicicnt to forms shoe, such piecelying upon the top of the standard of the machine-frame, below the anvilU, and in rear of the mould-block r, or between it and the eX-pellerortnppct the wings H H closed, the portlnn f of the wiper a,

By the time the culiritg-bar a has reached its highest posit-ion, thelongest point e of the wipcrc' strikes the mile! at, and completesthci'crward movement of the yoke X, and the straightening of the toggles\V Ti v This straightening of the toggles W: Wf co the deuce it oi thepuuch cnrrler it, and the sliding ba'r Y, carrying urn-prongs 1; 1 thepunches having the effect of wnolly or partially punching the nail-holesin the shoe, and the prongs having the effect oftapefln'g. the cultsfiunwi by the calking bar a, it being borne in mind that the lower endof the punch-carrier, or that enclosed within the radius efi rows ofpunches, well as the upper surfnceof the-m0'uldblock,zar6 ofsuchconilgumtlon as give the necessary shape or curve to the fire-cs of theshoe. g Thedesceutnf the punch-carrier, as it pnsses by the orificeuglhfin c mentioned, has the cflect-of severin the slim-strip at thispoint, preparatory to rem revolution of as driving-shalt of the machine.

It should also he borne in mind at this point, that as the anvil orclamp U is resting'upon the mould;

block during. the lest part of the descent of the punchcerrier, syielding connection between such clamp and carrier becomes necessary, 4

The shank and spring, before mentioned,"providc' for-this necc-ssity. f'L It will also be well to call the readers attentiob, I this point,to-the'fnct that the lower part ofthe punchcarrier, and preferably thatof the punches tbeumelva, should be hollow, and should contain water forMI ing the temperature of these parts, as well as that!!! the completedshoe, which otherwise would injure or incapacitate them, and cause acessstion ofiworkin'gof L the machine, I p r As soon as tho point-eofthe wiper o passefi b the roller 'm', the toggles-are suddenlycont-meted y I suitable cz'nn, spring, or other device, and the-punch-.carrier and sliding bar Y are suddenly elevated.

After passing' the roller m,the point a of the wipe:

The machine, constructed asahove described, is very compact in bulk, andmay be built at moderate gosh this means advancing. its iongeiarm,on'dsifzth it the I r feeding-carriage, which, in turn, carries with.it; the i its elements or mecinmicai movements are all positiveshoe-strip, and inserts such strip anew to fire action i of. themachine.

Soon after. passing the tripper, the wiper o strikes the roiler t of thelong lever s, and pushing thei'ree end of such lever ontwgrrd, causesthe carriage g to slide over the'shoc-strip', anti take a, fresh gripthereupon.

I have now shown how the nail-strip is fed into the machine, and out tothe desired length, and how it is' bent into shape, and nionlderl andpunched; v

I will now explain the action of that portion of the machine forexpelling the perfected shoe, and to do this, I go'back to the point andtime at which the; 'wiper o is impinging against, and mt-noting thetripper 0 and adwincing the shoe-strip;

At this point, the largest portion or point of the wiper or cam c, whichis somewhat in rear of that of the wipelzo, comes in contact with theroller b, and advances the'tappet m", and expo-ls the shoefrom themachine, the anvil, punch-carrier, and. eaiking-har, at this time, beingat their highest positions.

After passing by the roller 2 the wiper c" strikes the curved rear arm aof the pallet, and retracts its arm a, and with it the 'ta-ppet,substantially as hei'ore explained.

It will he ohrions ihat while the wiper 0 is impinging against thetrippcr rrrnd the roller t', the toggles W W'nnd J J are beingcont-racial or short-j cried, and, as a conscqnencg thePIJUClJ-Cfll'fliil ii l'lfl milk-tapering bar elevator], and the wings Hlf'o'jiened,
